LIGHT n'r'racnmnnr ron SEWING-MACHINES.

and ANGELO TQFBERTOIJNI, citizens of the i United States, and residents,respectively, of

'Poughkeepsie, in the county of Dutchess and State of New York, and thecity of New York, borough of the Bronx, in the county of Bronx and Stateof New-York, have invented a new and Improved Light Attachmentfor lowingis afull, clear, and exact description.

This invention relates to a lamp attachment. for sewing machines,whereby the rays of light can be thrown in any desired direction forproperly illuminating'the Work.

The generalobjects of the present invention are to improve theconstruction of light attachments for sewing machines so as to be reli-abl-eoind efficient in use, comparatively simple and inexpensive tomanufacture, and designedas to provide for the universal adjustment ofthe vlamp while the attachment is applied to the arm of the sewingmachine.

A more specific object of the invention is the provision of a novelbracket having attaching means especially designed. to en- ,g'z'ige inan oil hole in the arm of the sewing machine, whereby the bracket can befirmly held in place While the lamp adjustable to various positions toproduce the best illuminating efi'ects.

Still another object of the invention. is to provide a novel. connectionbetween the bracket andthe lamp-carrying arm, Where by the lamp iscapable of adjustment to various positions. a

The bracket 1- comprises an arm which has at one end asaddle 6 whichengages over the arm A of a sewing machine, as shownby'dotted lines in Fig:- 1. This saddle. or embracing portion 6 has alaterally extending lug 7 from which d'epends'la stud 8. This stud 8 isadapted to enter a lubricating opening 9 in the arm of the sewingmachine. The stud 8 has an internal'ly threaded bore 10-, and the lowerend of the stud is'split longitudinally to form jaws 1'1, and threadedin the stud is a longitudinally movable Wedge 12 which spreads the yawsll so that they snugly fit in the opening 991. the sewing machine arm,and thereby anchor the bracket 1 on the arm. The Wedge has a slot 13into which a screw driver can enter in order to turn the wedge andthereby move it longitudinally. The bracket extends outwardly from thesewing machine arm in a horizontalposition, and the outer end of thebracket has an upstanding car 14. An L-shaped secondary bracketconnected by a pivot 16' with the ear 1%, and on this secondary bracketis mounted thetuhulararm 2.
